A multidisciplinary team of Medical College of Wisconsin gastroenterologists and hepatologists works with other Medical College of Wisconsin specialists (surgeons, radiologists, oncologists, interventional radiologists, radiation oncologists, pathologists and others) to diagnose and treat a wide range of diseases of the gastrointestinal tract and liver.
These physicians work with physician assistants, nurses, dietitians and other team members to provide comprehensive care.
